It is understood that at present, access control systems in China are still mainly based on access control magnetic cards, fingerprints, and password locks. These access control settings often require residents to manually touch them at close range to open them. Frequent contact is both unsafe and unhygienic. The recently popularized facial recognition access control system advocates using "face" instead of "access card" to minimize unnecessary contact.

The facial recognition access control system mainly collects facial information through a camera and compares it with a large number of facial templates in the background. If it is confirmed to be a resident of the community or floor, it can pass freely. In this way, even if you forget to bring your magnetic card, your fingerprint is deformed, or you forget your password, you will not be blocked at the entrance of the community. "Face scanning" for entry is safe and hygienic.

Communities have concentrated populations and complex personnel entry and exit situations, including relatives and friends, express delivery and takeout, as well as unknown strangers. Due to the large flow of people and the energy limitations of management personnel, the management of entrances and exits has not been ideal. In addition, problems such as lost magnetic cards, leaked passwords, and stolen fingerprints have not been effectively solved, allowing many illegal elements to infiltrate, leading to frequent security incidents in the community.
The facial recognition access control system combines facial recognition, facial comparison, and the Internet of Things to achieve cross-verification of identities, assisting community management personnel in accurately identifying users. It is understood that due to the intuitive nature of faces and their difficulty to be copied, the facial recognition access control system can effectively prevent strangers from entering and leaving the community at will, minimizing the frequency of community security incidents, and strengthening the community security system.

With the rapid development of facial recognition technology, the optimization of facial recognition access control has gone a step further. At present, the recognition rate of facial recognition technology is no longer affected by external factors such as makeup techniques, portraits, mask models, day and night. It is difficult for strangers to enter the community gate through disguise.
Compared with traditional access control systems such as fingerprints and magnetic cards, the facial recognition access control system is more intelligent and convenient in management applications. In the past, when community personnel changed, it was necessary to promptly replace fingerprints, magnetic cards, and keys. After the application of facial recognition access control, new residents only need to register their facial information at the community management office to enter and exit freely, greatly saving the management costs of personnel changes in the community.
As the first line of defense for residential security, the importance of access control is self-evident, and the design of access control systems has become a focus of attention in the security market. In the current flourishing era of artificial intelligence technology, facial recognition has emerged, leveraging this trend to further push facial recognition access control into the market. Currently, facial recognition access control systems have been applied in fields such as finance, security, education, office, and building management.
